Portainer Community Edition is a lightweight service delivery platform for containerized applications that can be used to manage [[id:df046fd7-1f82-4e12-9065-56d222f56408][docker]], Swarm, Kubernetes and ACI environments. It is designed to be as simple to deploy as it is to use. The application allows you to manage all your orchestrator resources ([[id:936191f2-696b-4d9a-96ad-c8449778ae26][containers]], images, volumes, [[id:9d04fac3-89ae-4a96-b326-9ae7e2c22118][networks]] and more) through a ‘smart’ GUI and/or an extensive API.
|
||
|
||
Portainer consists of a single container that can run on any cluster. It can be deployed as a [[id:5fada795-19a3-4ba6-97c0-0b70bd728a2f][Linux]] container or a Windows native container.
|
||
|
||
This container is deployed to oversee all deployed docker containers. You can create the container with the following commands:
|
||
|
||
#+begin_src bash
|
||
docker volume create portainer_data
|
||
docker run -d -p 8000:8000 -p 9000:9000 --name=portainer --restart=always -v /var/run/docker.sock:/var/run/docker.sock -v portainer_data:/data portainer/portainer-ce
|
||
#+end_src
|
||
|
||
* Multiple [[id:f2b1d5af-1a7d-47a5-95c8-4a85d558419e][server]]
|
||
Portainer can be used to manage multiple instances of docker (servers). For that to be possible a second portainer container has to be deployed on the machine that is added to the main portainer manager. [[id:673d1cb1-536b-42f1-a046-40a8937c4283][root]] priv. needed ([[id:dc54334e-afa9-4a53-be91-1e90bc6bf8d0][sudo]]).
|
||
#+begin_src bash
|
||
sudo docker run -d -p 9001:9001 --name portainer_agent --restart=always -v /var/run/docker.sock:/var/run/docker.sock -v /var/lib/docker/volumes:/var/lib/docker/volumes portainer/agent
|
||
#+end_src
|
||
For that to work, the port has to be accessible from the main portainer instance. After the conatiner is spawnd, access the additional instance through the portainer [[id:a08570b0-8fe8-45a8-8f60-e45ea6b31a34][GUI]] on port 9000 and add it via the environment tab as a swarm instance.
|
||
|
||
* Stacks
|
||
Portainer has a feature for controlling Docker Stacks (multiple containers that act as a complementary unit). To do that, the containers need to be started as a stack inside the portainer UI. This must be done as a docker compose file. Thzis file can be either created in portainer or imported from different sources. you can controll all containers in a stack at the same time to stop/start the whole unit.
